- A logic for reasoning about responsibility.
DE LIMA, TIAGO; ROYAKKERS, LAMBER; DIGNUM, FRANK // Logic Journal of the IGPL; Feb2010, Vol. 18 Issue 1, p99One way to allocate tasks to agents is by ascribing them obligations. From obligations to be, agents are able to infer what are the forbidden, permitted and obligatory actions they may perform, by using the well-known Meyer�s reduction from obligations to be to obligations to do. However, we...
